Today, we’ll look at the accuracy of the Air Arms TX200 Mark III at 50 yards. I can tell you that I learned a lot from this test. But that will all be summarized as we go. Let’s get started!
I shot the new TX directly off the same sandbag that was used at 25 yards. As you remember, I showed (after much coaxing from you readers!) that the TX shoots as well or better when rested directly on sandbags as it does with an artillery hold. The bag was crossways to the rifle, so the contact with the stock was minimized.
The day was perfect for the test. Not a breath of wind the entire time I was on the line!
The rifle is mounted with the AirForce 4-16X50 scope, which was selected so I could conduct another test for reader Duskwight after the regular test was completed. This scope is clear and sharp; and at 50 yards, I was able to bisect the small bullseyes with the reticle.
The rifle was still zeroed for 25 yards, so it had to be adjusted for 50 yards before anything else could happen. The first shot landed 3-1/4 inches low and 1-1/2 inches to the left. It then took another 2 shots before I was reasonable on the target. Then, I fired the first group with H&N Baracuda Match pellets. Ten landed in a group measuring 1.562 inches. It’s a fairly round group, but not as small as I would like from this rifle. So, I switched pellets.
JSB Exact Monsters
Next I tried some JSB Exact Monsters, which weigh 13.4 grains in .177 caliber. They went all over the place. When I went dowrange to retrieve the target, I saw that they were tumbling or yawing. They must be too heavy for the velocity the TX is able to generate.
Crosman Premier heavy
The third pellet I tried was the Crosman Premier heavy. I meant to bring Crosman Premier lites, but I grabbed the wrong box when loading up for the range. Fortunately, the heavy pellet was wonderful! Ten of them gave me a group that measured 0.658 inches between centers — or about as good as a top-flight PCP can do at the same distance! This is phenomenal accuracy for any air rifle at 50 yards!
First lesson learned
The new TX200 Mark III is every bit as accurate as my TX that’s well broken-in. No accuracy has been lost over the years, and the rifle can shoot this well right out of the box!
With lesson one under my belt, I adjusted the scope to lower the point of impact and moved to the next bull. The first shot landed where the last group was, then the pellets moved to the new sight adjustment.
Second lesson learned
Some scopes have stiction. After adjusting them, it’s best to shoot a couple shots to vibrate the reticle to its new location. I knew that, but made the mistake anyway. So, I’ve included the first shot, along with the group, to show you what it looks like. If this group had been as small as the one before, that first shot would really stand out. But I lost my concentration on this one and wasn’t holding the rifle as softly as I might have. This group of 10 measures 1.435 inches between centers, which isn’t that far from the first group of H&N Baracudas!
The second group of Premier heavies opened to 1.435 inches. That’s more than double the size of the first group! Top hole to the left of the pellet was the first shot, which I disregarded, after the scope was adjusted.
Third lesson learned
While a rifle may be capable of shooting 10-shot 50-yard groups smaller than one inch, it may not do it every time! That small group may represent what the rifle is capable of, but not what it will always do.
Duskwight, our blog reader from Moscow, asked me to test the difference between a rifle shot with a low-power scope and the same rifle shot with a high-power scope. In other words, does magnification improve a rifle’s ability to group?
Well, common sense tells us that it does. Right? I mean, surely, if you’re able to parse the target to a finer degree, you must be able to group your shots closer together. Right? That’s what this test will determine.
That’s why I used a 4-16x scope on this rifle. I’d been shooting with 16x to this point, so now I dialed the power back to 4x and shot another group.
Wow! At 4x, the intersection of the crosshairs almost completely covers the small bullseye at 50 yards. As I shoot, I’m almost certain how this test is going to turn out. And it does. Ten shots on 4x with the same Premier heavy pellets landed in 2.208 inches. Looks like I was right about what low magnification would do.
The third group of Premier heavies — shot with the scope set to 4x — was 2.208 inches between centers at 50 yards. That’s quite a difference from the previous group, even though that group was already admittedly large.
But something nagged me about this group. I knew in my heart that I’d not given the rifle my best. I knew this group was going to be bigger than the last one while I was shooting it, so I was even sloppier with my hold.
It probably sounds like I need medication to suppress my dual personalities while at the range, but I assure you I’m not talking to myself — at least not loud enough for others to hear. What I’m doing is a little soul searching while I’m still out at the range and have the time to do something about it.
I adjusted the scope back to 16x and shot another 50-yard group. This time, I did everything the way I should have. The hold was completely relaxed. I fully expected to be rewarded with another of those sub-inch groups, but that didn’t happen. This time, I shot a 10-shot group measuring 1.935 inches between centers. Oh, well! I was probably tiring out from all the concentration.
Fourth lesson learned
Sometimes, you just can’t will the results to happen the way you would like. I put my whole heart into this group, and this is what I got. Maybe that’s what it feels like to be 66, dried-out and ready for the old-folks home!
Fifth lesson learned
I called that first great group of Premiers a screamer. Now you see why that is.
Nevertheless, I owed it to Duskwight to try the rifle on low scope magnification one more time, and this time to do my very best. So I did. This time, 10 pellets went into a group that measures 1.481 inches between centers. That’s right, it’s SMALLER than the group shot on 16 power! I noticed that the bull was just visible behind the crosshairs; and if I really tried, I could hold on the target in exactly the same way every time. Apparently, I did, because this group fired on 4x is smaller than the previous group that was fired on 16x.
Sixth lesson learned
Although it isn’t conclusive, it looks like you can shoot just as accurately on low scope magnification as you can on high magnification if you take the time to do things right.
Seventh lesson learned
Looking at both groups fired on 16x and both groups fired on 4x, it sure looks like the point of impact never changed! Some of you have asked about that in the past. The design of the scope determines whether the impact point will move when the scope’s power is changed, but these days a lot of variable scopes stay right where they were when the power’s adjusted.
Eighth lesson learned
Of the five groups fired with Premier heavy pellets on this day, only one is smaller than one inch. And it’s significantly smaller! When you see those great groups in the future, you must ask yourselves what the rest of the groups look like.
Ninth lesson learned
I may be old and dried-out, but I can still shoot — a little. I get tired as the shot count increases, so that needs to be factored in to my tests from now on.
I’m very pleased with what this new TX200 Mark III has done so far. I think the rumors that the TX quality may have slipped are just that — rumors! Individual guns may have problems; but overall, the TX200 is one fine air rifle. Next, I plan on mounting a red dot sight and testing it for accuracy, again, to see what the differences are.

Not as pretty as I would like. This Diana 23 has led a hard life. I’ll refinish it.
Today, we’ll return to an oldie we haven’t looked at in close to 2 months — the Diana 23. You may remember this is a rifle I bought for very little from an online auction — and when it arrived, I found it was better than expected. The finish is gone, but I plan to refinish it. And Larry Hannusch generously donated a brand-new old-stock Diana 23 barrel for the project, so I’m farther along than might be expected.
Last time, we tested the rifle at 10 meters and found that it showed decent accuracy for such a low-powered air rifle. Today, I’m pushing that out to 25 yards with 2 of the best pellets from the last test, plus a new one I’ve thrown into the mix. The goal is to see if this little vintage springer is accurate enough for general plinking duty out to 75 feet.
Days like this are always relaxing for 2 reasons. The first is that I’m testing something that’s no longer available, so there are no company reputations on the line. I enjoy testing airguns, but it’s disturbing to read all the sniping negative comments we receive when things don’t go exactly perfect. It makes me feel like I have failed the gun somehow, and that’s nerve-wracking.
The second reason a day like today is a pleasure is that the gun, itself, is such a little sweetie. The Diana 23 is lightweight and easy to cock. The trigger is certainly not world-class, but it releases with a reasonable pull; and, if the gun is also accurate with open sights, all the better.
I find when I shoot light low-powered airguns like the 23, the artillery hold isn’t so important. I grasp the rifle tighter than a real artillery hold, though not as tight as I would hold a recoling centerfire. Maybe something more like a rimfire hold. The rifle seems to respond okay to this treatment.
JSB Exact RS
The first pellet I tried was the JSB Exact RS dome. They did well in the 10-meter test that I read before starting this one. I noted that deep-seated pellets did best in that test, so all pellets in this test were seated with the Air Venturi Pellet Pen and Pellet Seater. The RS pellets fit the bore very well and were not tight going into the breech as they were seated. They hit the target high and just a little to the right when I held the tip of the front sight on the 6 o’clock spot of the black bull. I used the standard 10-meter pistol target because it appears large enough for open sights all the way out to 50 yards.
The group I got measures 1.16 inches between the 2 furthest centers. I’m quite satisfied with that group, except for the centering. The way the 23′s sights are made, I’ll have to drift either the front or rear sight in their dovetails to correct where the pellets land; and since I’m going to change the barrel, I decided to wait and see where the new one shoots.
Air Arms Falcon
The second pellet I tried was the Air Arms Falcon that blog reader Kevin Lentz likes so much. They’re made by JSB and weigh the same as the RS pellets, so the temptation is to think they’re RS pellets under a different name. But I don’t think that’s the case. The late Bill Saunders of Air Arms told me that Air Arms owns the dies for all their pellets; and even though JSB makes them, they’re not simply rebranded pellets. If anything, Falcons fit the bore a little looser than RS pellets.
At any rate, Falcons didn’t do as well as RS pellets in the Diana 23. Ten of them made a group that measures 1.568 inches between centers. This group appears not to have 10 shots in it, but several pellets must have gone through the same hole at the top of the group because I counted each shot carefully.
The final pellet I tried was the RWS Hobby wadcutter. They fit the bore very snug and popped in when seated. Though they were at the outside limit of distance for accuracy (wadcutters start to spread apart after 25 yards), they performed very well — delivering the smallest group of this test. Ten pellets went into 1.014 inches at 25 yards. With that kind of accuracy, I would stick with the Hobbys that are less expensive than the other premium pellets anyway. Sure, the accuracy falls off as the distance increases, but how much farther do I expect to shoot this rifle? Not much!
That’s all I’m going to test for now. Next comes the refinish and then whatever I do as I put the rifle back together. It’s a fun little gun. I wish there were more like it!

I’m writing this extensive report to fully explore the fabulous Air Arms TX200 Mark III, which is without a doubt one of the finest spring-piston air rifles in the world! The good news is that it’s still available today. The better news is that it’s everything it’s cracked up to be! Writers have a few trite phrases to convey quality in the airgun world. “As good as a TX 200″ is one of them, and it’s very high praise.
There are 9 links above that will take you all the way back to the beginning, when I started by testing my own well-broken-in TX 200. But now I’ve shifted over to a brand-new rifle that Pyramyd Air sent to me to test. Some readers wondered if my rifle, which is so well-used that it might be performing above the bar, so to speak, because of the use it’s had. They wanted to see a rifle that’s being made today, and also one without all the wear on the parts. That’s what we’re testing now — a brand-new TX whose only shots are the ones you have witnessed on this blog.
The TX has no sights and must be either scoped or have some other kind of optical sight mounted. One of the tests we’re going to do with this rifle is to mount a red dot on it and see what that does for it. Blog reader Mannish from Mumbai asked for that test a long time back.
We’re also going to test the effects of shooting the gun at 4X and again at 16X with the same scope. Reader Duskwight asked for that — to see if the increased magnification would affect the group size. I also want to see if changing the magnification changes the point of impact, so that test will be a twofer.
I’m leading up to the scope I chose for this test. I might have selected the same Hawke 4.5-14X42 Tactical Sidewinder that was on my TX when I tested it, but that didn’t give me all the magnification I wanted for Duskwight’s test. So, I selected a vintage AirForce 4-16X50 scope, instead. Mine is older than the model being sold today, but the specifications are essentially the same. For a mount, I selected a nondescript 1-piece mount. I chose it because it has a vertical scope stop pin for the TX scope stop holes, plus it has the height needed for the scope’s objective bell to clear the spring tube. I have no idea who made it.
I started sighting-in at 12 feet, putting 3 pellets into the target and adjusting until they were in line with the center of the bull, more or less. They were high, so I cranked down about 4 complete turns on the elevation knob, knowing that back at 25 yards the gun would be shooting higher than at 12 feet.
When I shot the first pellet at 25 yards, it was still about 1.5 inches high, so a couple more turns down on the elevation knob brought it to the center of the bull. As always, I tried to intentionally keep the pellets from striking the center of the bull, as that erases my aim point very quickly. The sight-in was now complete with about 7 shots being expended.
All of today’s shooting is at 25 yards, which is really close for a TX. I rested the rifle directly on my sandbag, with the bag turned sideways, so the rested area touched about 5 inches of the forearm. I used an ultra-light hold, and the groups showed the results. I selected a couple pellets that had done well in the test of my personal TX and one that had never been tested for accuracy before.
H&N Baracuda Match
The first pellet was the one I used to sight-in the rifle — the H&N Baracuda Match. It was landing to the left of the aim point and in the center of the bull for elevation. Ten shots landed in a group that measures 0.417 inches between the centers of the 2 pellets farthest apart. That’s well within the range fired by my personal TX at 25 yards.
JSB Exact RS
Next, I tried a pellet I haven’t tried for accuracy in the TX — at least not that I can remember. The JSB Exact RS dome is a very lightweight pellet for a rifle this powerful. The first shot landed about 1.5 inches above the spot where the Baracudas were hitting, but it was still on paper, so I continued to shoot. Each shot that followed seemed to drop a bit lower on the paper, and as I was shooting I discovered something important. The rifle shoots this pellet very well, but it is extremely hold-sensitive. Moving the rifle a quarter-inch on the sandbag makes a tremendous difference. So, I was able to adjust the hold carefully and get the pellets to land closer together.
I think the RS pellet can be made to shoot, but it isn’t worth the effort when there are other pellets that shoot even better without all the fuss. The 10-shot group I got measures 1.501 inches between centers, which is terrible; but 6 of those pellets were the ones I took special pains to hold exactly the same, and they measure just 0.496 inches between centers. That’s the potential of this pellet when you handle the gun like it’s a soap bubble!
Crosman Premier heavy
The last pellet I tested was the Crosman Premier heavy. The group was a phenomenal 0.333 inches between centers! That’s slightly better than the best group I shot with my own TX at 25 yards, but the difference is only 3 one-thousandths of an inch and could easily be hidden by an error in measurement. So, the 2 rifles are equivalent.
I could have shot other pellets and shown you more targets, but by now you’re getting the picture. The new TX is the same as it has always been — one of the finest and most accurate air rifles on the market.
Next, I’ll test this rifle at 50 yards. I’ll do essentially the same test that I did with my own TX at that distance, but then I’ll add the 4-16X test. That will tell us if there’s an advantage to more magnification, and it will also show if the point of impact changes as the magnification changes.
After that test, I plan on mounting a red dot sight on this rifle and testing it at 25 and 50 yards. I think that will end the test of this rifle, unless something else comes up.

Today, we’ll test the Umarex Fusion CO2 rifle at 25 yards. And today was also supposed to be the day I tested how long you have to wait to remove the CO2 cap after exhausting the gas. That’s not going to happn, though; because when I took off the CO2 cap to install 2 fresh CO2 cartridges, I noticed the o-ring was damaged pretty bad. So bad, in fact, that it might not work any longer. I switched it for a common black Buna o-ring of the same size and then charged the gun. At the end of this report, I’ll tell you how that works.
JSB Exact RS
When I tested the rifle at 10 meters, the best pellet was the JSB Exact RS dome, so that was the first pellet I tested this time. As I predicted after shimming the rear scope ring, the rifle was hitting too high at 25 yards. I had to drop it about 2-1/2 inches and move it to the right about three-quarters of an inch.
The first 10-shot group I fired measures 0.523 inches between centers. It’s nice and round, also. Remember, I’m using the 4x scope that came with the rifle, so the bullseyes looked pretty small at 25 yards. Also keep in mind that this shooting was done indoors, so wind is not a factor.
The first group looked so good through my spotting scope that I shot a second one with the same RS pellets. This time, 9 of the pellets went into 0.455-inches, but one shot opened the group to 0.688 inches. That wild shot was not a called flier; it just went astray.
This second group of JSB Exact RS pellets measures 0.688 inches between centers.
H&N Baracuda Match
The second-best pellet at 10 meters was the H&N Baracuda Match, so that was the next pellet I tried. Ten landed in a 0.625-inch group that’s open but fairly round at the same time. Looking through the scope, this group didn’t look very promising; but I see upon inspection that it isn’t much worse than the first 2 groups.
Air Arms Falcon
The final pellet of the day was the Air Arms Falcon dome, which is made by JSB. Sometimes, this pellet surprises me with stellar accuracy. This time, 10 pellets made a group that measured 0.56 inches between centers. It’s very close to the first group of JSB Exact RS pellets, which turned out to be the best group of the day.
The new o-ring
The new o-ring worked, but there was some leakage when I pierced the cartridges. The gas exhaust screw wasn’t the culprit this time — it was the o-ring that leaked. I suspect I selected a ring that is too thin for the job. When I removed the cap, I saw that this ring had also absorbed the gas and swollen quite large. I took a picture of it 5 minutes after taking it out of the gun and again after 45 minutes, so you can see the dramatic difference as the o-ring outgasses and shrinks back to normal.
There’s a lot to like about the Fusion air rifle. It certainly is accurate, and it fully delivers on the promise of quiet operation. There aren’t many other air rifles in this price range that can compete. Even the scope that comes with the rifle seems to be up to the task.
While today’s groups are not stunning, they’re all good. It’s interesting to note they’re all under three-quarters of an inch and some approach a half inch.
I do think the o-ring that comes with the rifle needs to be changed to something that doesn’t swell. And it would be nice if the trigger was more adjustable. But those are small points. If you’re looking for a fun plinker that’s both quiet and accurate, put this one on your list!

Today is the first accuracy test of the Umarex Fusion CO2 rifle. It comes one part late because we spent time looking at the CO2 cap, the adjustable trigger and the power adjuster in Part 3. The power adjuster is straightforward — twist the screw in and increase the striker spring tension to increase power. The trigger, we learned, is adjustable, but the safety slider prevents a very wide range of adjustability. You can modify it if you choose, but I don’t recommend it; and it will void any warranty on the gun. Blog reader mikeiniowa explained how it’s done, but he said to use caution — and I don’t intend doing it to the test gun.
You should now understand how the CO2 cap works, but there’s one additional thing that I think needs to be stressed. The gas exhaust screw on the cap is to use after the CO2 has been depleted. Screw it in and exhaust the remaining pressure. But that isn’t the end because the cap still cannot be taken off safely, as a reader mentioned yesterday. The o-ring that absorbs gas has to be given a lot of time to exhaust that gas and shrink back down to normal size before you attempt to remove the cap. If you try to remove the cap too soon after exhausting the gas, the o-ring will still be swollen and tightly wedged in place. You could tear it if you use too much force on the cap. So, let an hour or two pass before you try to remove the cap; and leave the exhaust screw screwed in, so the remaining gas that leaves the o-ring can get out of the gun. Anyone who has ever owned a Schimel CO2 pistol knows what I am talking about because they had the same problem.
Mounting the scope
The Fusion comes with a 4X32 scope and rings that must be mounted on the gun. The rings are made to clear the rounded receiver top, so don’t think just any rings will work. I want to show you what one of the rings looks like after installation, so you don’t go nuts thinking it’s not on the gun squarely.
The Fusion receiver is rounded on top, so the bottom of the scope ring must be profiled to clear the hump. The rings that come with the gun are correctly shaped for this. Don’t let the cockeyed jaw piece fool you — this ring is on the rifle straight and tight!
The scope caps have 2 screws each, which is perfect for this gun. There’s no recoil, so 2 screws hold the scope tight enough for good accuracy.
Once the scope was mounted, I sighted-in at 10 meters. All of today’s shooting will be from 10 meters for reasons I will explain as we go. I’m telling you that because the groups will be smaller than if they were shot at 25 yards. I do plan on testing the Fusion at 25 yards, too, but first I have to establish what it can do closer.
One additional thing about the sight-in. All the pellets struck the target low at 10 meters. I accepted that for the whole test, and I had to adjust the scope up very high to even get that. You know how nervous that makes me! So, at the end of this test I’ll shim the rear scope ring and try one more group with the best pellet. The groups you’ll be seeing are either low on the bull or just beneath it.
JSB Exact RS
The first group was shot with the JSB Exact RS pellet. As I shot, I could see all the pellets going into the same place; although with the 4x scope, it wasn’t easy to see exactly how good it was until I went downrange. It turned out that 10 pellets made a 0.286-inch group, measured between centers. And this group is very round, which is a good sign that everything is right with the rifle.
I observed several things while shooting the first group. The first is the trigger, while having a very long second stage pull that you can feel, is very controllable. Next, I did find the rifle just a bit fiddly to load. Once I got the hang of it, however, I was able to load pretty fast. But the pellets tend to flip around in the trough — especially the domes!
And, finally, I noted how very quiet the Fusion is! Our female cat, who usually walks around the house complaining every time I shoot, found it hard to hear what I was doing unless she was in the room with me. Even then, the noise didn’t seem to bother her, though Edith did say she walked into her office to complain once. Other than that, she was quiet. I think any apartment-dweller could shoot this rifle indoors without bothering the neighbors.
H&N Baracuda Match
Next, it was time to test the H&N Baracuda Match pellets. They landed higher on the target than the RS pellets but were still below the point of aim. This group measured 0.345 inches and was just as round as the RS group.
Crosman SSP hollowpoint
Then I tried the lightweight lead-free Crosman SSP hollowpoint. I didn’t expect much from these pellets, but I tried them because I’d used them in the velocity test. They produced a 10-shot group that measures 1.66 inches between centers. Obviously, I’m not going to shoot this pellet at 25 yards and risk hitting the walls of my house or the furniture! This is why I started shooting at 10 meters.
The last pellet I tested was the RWS Hobby wadcutter. Ten went into 0.59 inches at 10 meters. But the first pellet went to the left of the next 9, so I think this might be one of those times when conditioning the bore was required for best results. Not that I believe in that theory, mind you, but this time it really looked like that’s what was happening. The 9 pellets went into 0.36 inches — a much better showing! The Hobby is the third best pellet in the test, but I think the group of 9 is more representative of what it can do.
The JSB Exact RS and the H&N Baracuda Match are the 2 pellets I’ll test at 25 yards. I would include the Hobbys, but 25 yards is right where wadcutters start to spread out, so I’ll just go with the 2 domes. However, there’s still one more thing to try today.
I removed the scope and put one plastic shim on the bottom of the rear ring under the scope tube, then installed the scope again. I went back to 10 meters without any sight-in shots and shot one more group with JSB Exact RS pellets. The group moved up over 1-1/4 inches and over to the left by a half-inch. This is where I will begin shooting at 25 yards, knowing that I’ll probably need to decrease the elevation to get back on target. Isn’t that interesting, that the point of impact moved up so much with a single shim? The shim measured 0.013 inches, by the way.
Ten JSB Exact RS pellets went into 0.244 inches at 10 meters. It’s the best group of the day! This group was fired after a 0.013-inch shim was placed between the scope and the rear ring. The scope was then simply remounted and no sight-in was done. This group is about 1.30 inches higher than the first group. It also appears to be smaller, but the dark paper hides the true size of the pellets.
Impressions so far
The Fusion is a winner! I like everything about it. It has taken some time to understand; but now that we’ve been through the design and know what to expect, you show me another air rifle that costs $170 and shoots like this one. We’re talking groups very similar to what vintage 10-meter target rifles can produce.
No — it’s not a good rifle for hunting; and, no, I don’t think it can be modified to become one. If that’s what you want, get a Discovery. Leave the Fusion as it is — a nice, quiet, accurate rifle.
25-yard testing yet to come.

Umarex Fusion CO2 rifle
Today, we test the Umarex Fusion CO2 rifle for velocity and several other things you readers are interested in. You may remember that in the first part I had a problem with the rifle not sealing when I loaded the CO2 cartridges. Blog reader mikeiniowa nailed the problem with the Fusion CO2 cap. The part that contains the piercing pin was partially unscrewed and was, therefore, longer than it should be. It was piercing the cartridges before the o-ring was in position to seal the gun. So, a lot of gas leaked out; and, because the o-ring absorbs CO2 and swells when it does, it also prevented the cap from being screwed down tight.
I’m going to show that cap in detail in a later report. It’s made so complex because of the material the o-ring is made from. If a different material had been used, none of the complex parts would be needed…and the cap could be made for less cost.
So, with the cap assembled correctly, I was able to load 2 fresh CO2 cartridges. This time, everything worked as it should, and the velocity test began.
JSB Exact RS
The first pellet I tried was the 7.3-grain JSB Exact RS. This lightweight dome is a winner in many lower-powered air rifles, and I believe the Fusion will be one of them. The first shots started slow, at 619, 647 and 644 f.p.s. Then, the velocity jumped up to 663 and remained above that number for the remainder of the string. The average, once the velocity was in the curve, was 667 f.p.s. That means the Fusion’s valve needs to be awakened after installing fresh cartridges.
The low velocity, once the pellet had climbed into the stable spread, was 663 f.p.s., and the high was 673 f.p.s. At the average velocity, the RS pellet produced 7.21 foot-pounds of muzzle energy. Because the Fusion is a gas gun, we can expect the power to increase and decrease with the pellet weight.
I tested the same pellet several hours later, and the first JSB RS out the spout went 686 f.p.s., so the velocity had increased by 20 f.p.s. after 40 shots had been fired and the gun then rested for 3 hours. But that was also the end of the power curve. By shot 50, the velocity of all the pellets started to drop again.
The second pellet I tried was the 7-grain RWS Hobby wadcutter. They averaged 669 f.p.s. with a spread from 661 to 681 f.p.s. At the average velocity, this pellet generated 6.96 foot-pounds of energy at the muzzle. Lighter pellet, less energy.
Crosman SSP hollowpoints
The third pellet I tested was the Crosman SSP hollowpoint. Remember, Umarex lists the velocity of the Fusion at 750 f.p.s. with lead-free pellets (which they call alloy) and 700 f.p.s. with lead pellets. I should have tested the rifle with RWS HyperMAX since those are the ones Umarex imports and distributes, but I didn’t have any on hand. Anyway, the Crosman pellets worked fine. They gave an average 766 f.p.s. velocity, with a low of 757 and a high of 783 f.p.s. At the average velocity, this 4-grain pellet produced 5.21 foot-pounds of muzzle energy, so it’s staying on track for the pellet-weight-to-velocity relationship.
After 50 shots had been fired, the average velocity for this pellet fell to 711 f.p.s. So, the velocity is going down, but the velocity is still useable up to 60 shots.
The last pellet I tried was the 10.6-grain H&N Baracuda Match. In a spring gun, the velocity for this pellet would fall off quite a bit from the numbers for these lightweight pellets, but gas guns and pneumatics are different. Heavy pellets don’t lose nearly as much velocity as they do in spring guns. The average for Baracudas was 612 f.p.s. The range went from 600 to 616 f.p.s. At the average velocity, the Baracuda produced 8.82 foot-pounds, which is significantly higher than any other pellet.
One of our readers mentioned that the total number of good shots he gets is about 70 shots with each set of CO2 cartridges. I was looking for about that number. I noticed the velocity began dropping at shot 50. But there were still 10 more good shots in the gun. From shots 56 through 60, the velocity for the baseline JSB Exact RS pellets was 622, 614, 603, 602, and 584 f.p.s. While there were still more shots to be fired, I felt that accuracy would probably drop off at this point. So, I’ll rate the Fusion I’m testing as a 60-shot gun.
And, now, we come to the question on everyone’s mind. Is the Fusion quiet? Umarex not only says that it is, they tout the low sound level heavily in their advertising campaigns. While I don’t have any scientific sound measurement equipment to test with, I can make a fairly good subjective observation of the gun’s report. I compared it to my Diana model 23, which most of you readers know to be a very small, low-powered spring-piston youth model air gun. The Fusion and the Diana 23 are approximately the same loudness. That means that the Fusion is a very quiet air rifle.
Blog reader Matt61 wondered if it would be louder than a ballpoint pen falling on a thick carpet, and I must say that it is. But it isn’t much louder. I think this is a gun you could shoot in an apartment that has thin walls separating you from the neighbors. You should be able to shoot in even small backyards without disturbing the neighborhood.
I told you the trigger is 2-stage. Stage 1 is light and relatively short. Stage 2 is also light but long and creepy. The sear releases at around 3 lbs., 12 oz.
Besides the accuracy test, which is expected, I also want to take the gun out of its stock and look for both the power adjuster and the trigger adjustment that reader mikeiniowa mentioned. I’ll use that report to also show you the details of the CO2 cap and explain how it works so you understand what’s going on.
Given the power level of the Fusion, I think I’ll start testing accuracy at 10 meters and then back up to 25 yards. If the rifle comes through the accuracy portion with honors, I’ll give it a hearty recommendation.
by Tom Gaylord, a.k.a. B.B. Pelletier
This is my second trip to the rifle range to shoot the TX200 Mark III at 50 yards. Last time, I shot only heavy pellets; today, I’ll shoot the hopefully more-accurate lightweight pellets, plus one JSB medium-weight pellet that several blog readers have had success with.
I also shot the rifle laying across the sandbag, instead of in the long groove down the center. Several readers said that was the best way to rest the rifle directly on the bag.
The day was perfect for shooting pellet guns at long range. There wasn’t a breath of air during the entire session.
The first pellet I tested was the Crosman Premier lite — a 7.9-grain dome that some say is the most accurate pellet of all in the TX200. The group landed about 2-1/2 inches above the aim point because the rifle was still sighted for heavy pellets. But it was centered perfectly, and 10 pellets made a group measuring 1.077 inches between centers. That’s not a bad group, but I’ve seen TX200s do better at 50 yards.
That was a good start. The group was only slightly larger than the smallest group fired in the session before, which was 1.042 inches.
Following the first group, I adjusted the scope down several clicks. I wanted to keep the shots on or near the bull at which I was aiming.
JSB Exact 8.4-grain dome
Next up was the JSB Exact 8.4-grain dome, a pellet that several readers said was the most accurate one in their TX200s. Alas, that wasn’t the case in my rifle. When the first 5 pellets landed in a very vertical 2.40 inches, I stopped shooting. There’s no way the last 5 shots can improve things. Clearly, this isn’t the pellet for my rifle!
JSB Exact RS
The next pellet I tried was one I had high hopes for — the 7.3-grain JSB Exact RS dome. It does so well in so many spring rifles; but, once again, the TX200 Mark III is not one of them. Ten pellets made a group that measured 1.957 inches. It’s a vertical group, as well.
Air Arms Falcon
About this time I was suspecting that the rifle does not like lightweight JSB domes. The next pellet up was the Air Arms Falcon, another lightweight domed pellet that’s also made by JSB. While Falcons are great in many air rifles, the first 5 landed in an open group measuring 1.658 inches, and I stopped right there. It looked like this pellet wasn’t for my TX, either.
What was happening?
Three out of 4 pellets I brought to the test were not good. Had I made a mistake with the Premier lites, as well? Was that good first group just a random event? I decided to shoot another one to see. This time, though, I laid the rifle the long way in the bag to see if there was any discernible difference.
Ten pellets went into a group measuring 1.241 inches this time. That is much closer to the first group than any of the other 3 pellets tried on this day, though it’s still larger. Maybe, laying the rifle lengthways made the difference? I don’t think so.
I decided to shoot another group with the rifle laid lengthways, again, just for comparison. This time I hit the jackpot and all 10 pellets went into 0.658-inches.
The TX 200 Mark III is capable of phenomenal accuracy at 50 yards, even when rested on a sandbag. From the limited testing I did I can’t say laying it crossways or lengthways is better. It works well both ways.
My rifle seems to shoot best with 7.9-grain Crosman Premier lite pellets. It does not seem to like any light pellets made by JSB.
This is not the end of our testing. Pyramyd Air has sent me a new TX200 Mark III that I promised you I would test right out of the box. Some of you have been concerned that my rifle is too well broken-in, and you think it may not reflect what you will get if you buy one. So, we shall see!
As a final note, I’d like to point out that I got several groups that were okay with the Premier lites and one group that’s exceptional. That’s the way it goes with any airgun — I don’t care which one you’re talking about. All the talk about half-inch groups at 50 yards has to be taken with this firmly in mind. You’re going to shoot larger groups most of the time.
That being said, Premier lites seem to be the most accurate and also the most forgiving pellet we’ve tested in my TX200. They may not always shoot into a super-tight group, but they’ll always shoot where you want them to. That’s what’s important.
